We’re doing this week’s Ad Astra post early because the European Space Agency is sending down the Rosetta mission’s Philae lander on Wednesday, November 12.
It’s going to attempt a landing on Comet 67P, according to the present schedule, at around 10:35 a.m. Eastern. Since there is a time delay due to distance (this is happening about midway between Mars and the asteroid belt), people on Earth won’t know if it worked until about a half-hour later.
No one knows what a comet’s surface is like, so we’ll all have to wait and see what happens.
The Livestream will be here, starting Tuesday. The ESA will have its webcast here, also starting Tuesday. NASA-TV will carry live coverage here from 9 to 10 a.m. Eastern on Wednesday and then will switch over to ESA coverage from 10 to 11:30.
